To all whum it mayconcem:

Be it known that I, WILLARD H. CoBB, a

York, have invented certain new and useful Improvements in Belt-Clamps,of whlch scription;

. This invention relates to belt clamps and hasfor an object to providea clamp for joining the ends of flexible belting, such as leather,rubber, balata, canvas and the like in such a manner as totransmitpower. for

constant or varying loads without increased stretch or slack said ends.A

In the ordinary; constructionof belt clamp, the ends of the belt arecarriedoutwardly at right angles to the longitudinal line-of the beltand there confined betweentwo', rigid clamp plates by boltspassedthrough the plates. As a result of this construction, the belt isstrained and mutilated by being pulled at right angles to itself againstthe sharp edges of the clamp plates and is thereby, weakened towithstand service conditions. The present invention obviates thisdisadvantage by the provision of novel guard-plates underneath the clampplates which relieve the belt from shocks incident to variable loads andprovide means for obtaining a more constant ten.-

same time allowing the belt to take an easy bend without damage.

The invention will be readily understood as to the accompanying drawing,in which Figure 1 is a plan view showing the application of theinvention to a belt;

Fig. 2 is a cross-sectional view on the line Fig. 3 is a sectional viewof a modified form of the invention.

Referring now to the drawings, 10 indicates the ends of a flexible beltof rubber, leather, balata, canvas or the like, the same being directedoutwardly at right angles to the longitudinal line of the belt, as shownin Fig. 2, and there confined togetherbetween parallel transverselydisposed clamp plates are passed.

plate llland a corresponding end of the at 14;, thereby presenting acurved face to the outer surface of the belt near the junction line 14of the clamped ends, to provide against mutilation of the belt whenflexing in passing over the pulley, or under other service conditions.Each guard plate is preferably formed of resilient material and receivesthe tension of and yields with the belt. The area of the guard platesand their capacity for yielding are regulated to meet service conditionsand permit of the belt taking an easy bend in passing over the pulleyswithout increased stretch or slack to the belt, this yielding capacityfurthermore relieving the belt from shocks and jars incident to variableloads and providing means for obtaining a constant tension notheretofore obtainable.

Each guard plate may be formed of rigid material 15 provided with arounded face 16 that bears against the belt 17, and each clamp plate 18maybe fashioned to anchorv the guard plate in place in any preferredmanner, as for instance, by bending the end 19 down over the clampplate.

The'gua'rd plates may be formed integral with or separate from the clampplates.

Also each guard plate may be formed (if a single piece of resilientmaterial, or of rigid material provided with a resilent free portion, itbeing simply necessary to the practice of the invention that curvedparts project from the clamping members to yieldingly receive thetension of and prevent mutilation of the belt under service disposedflaring edges adapting them to 11, through which and the ends, bolts 12yieldingly support theends of the belt at the bends thereof, rigidplates at the opposite edges and adjacent exteriorly of the first platesfor limiting resilient areas of said first plates, and locking boltsextending through the plates.
